CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national stage filing under 35 U.S.C. § 371 of PCT/US2016/026851, filed Apr. 10, 2016, which claims priority from U.S. Provisional Pat. App. No. 62/146,237, filed on Apr. 10, 2015. Each of the above-referenced applications is entirely incorporated by reference herein.

BACKGROUND

Bisphenol-A (BPA) is a cross-linker for synthetic resins used as coatings, and began to replace resins based on natural oils (oleoresins) in the mid-1970s. BPA-based coatings have high corrosion resistance compared to oleoresins and are widely used, e.g., in food packaging. In the United States, over 300 billion beer, beverage, and food cans are coated with half a million metric tons of BPA-containing epoxy resins each year, and the global market is more than twice that large. Although there are currently no U.S. Food and Drug Administration (FDA) or other U.S. regulatory restrictions on the use of BPA-based resins in most food containers, BPA-related health hazards have been recognized by regulators, policymakers, and consumers. Controversy over health implications has caused concern over the use of BPA in food packaging. BPA is banned from use in applications such as infant feeding plastic bottles, and California recently listed BPA as a hazardous material.

There is much interest in cost-effective and functional replacements for BPA-based epoxy resins in can coatings that may contact food. Desirable characteristics for alternative coatings are numerous and challenging, including coating integrity (adhesion, strength, flexibility, pH/corrosion resistance, and the like) under sterilization, handling, and storage, no effect on food taste, compliance with FDA guidelines on direct food contact use, cost-effective, compatible with established manufacturing processes, and the like.

Many attempts to develop a viable solution have been made. Natural oils may be functionalized with hydroxyl or carboxyl groups and may be converted to polyesters and polyurethanes for use in coatings, inks, adhesives, foams, and the like. However, oleoresins often exhibit poor corrosion resistance. For example, it is believed that acidic tomato juice readily damages oleoresin coatings. Chemistries such as vinylation, acrylation, polyesterifcation, polyolefinination, and use of a variety of cross-linkers have been explored, but have not been successful because of failure in one or more desirable characteristics, such as flexibility, adhesion, application method, cure speed, corrosion resistance, or hydrolysis under low pH.

Some epoxy-based resin alternatives have been investigated using alternative cross-linkers, such as diglycidyl ethers of n-alkyl diphenolates, isosorbide, and bisguaiacol. However, these alternatives are costly and have been reported to suffer from problems such as estrogen receptor activity, epichlorohydrin toxicity, and poor hydrolytic stability.

The present application appreciates that developing corrosion resistant resins. e.g., for replacing BPA-cross-linked resins in can coatings, may be a challenging endeavor.

Example 3: Soy-AAG Polyamine and Soy-AAG Polyamide Coatings

Examples 3A-3C below were performed as follows: The AAG and crosslinker (total 10 grams) were weighed in a Flecktec mixing cup along with PTSA (0.5-10 wt % in methyl ethyl ketone (MEK)). The contents were mixed at 3000 rpm for 1 min. The resulting mixture was coated onto a low carbon steel panel using a 2 mm wet film thickness drawdown bar. The panel was cured at 180° C. for 30 min.

Example 3A

75% soy-AAG: 25% CYMEL™ 303, PTSA (0.5%). It was observed from Thermogravimetric Analysis (TGA) that soy-AAG (“Soy-PK”) cures faster than its precursor: the non-acetoacetoatylated commercial bio-based polyol [Honeybee HB530, MCPU Polymer Engineering, LLC, Richmond]. The TGA plot of soy-AAG curing with CYMEL™ 303 is compared with the bio-based soy polyol curing with CYMEL™ 303, as shown in FIG. 3.

The degree of cure, a, can be calculated from the TGA data using the following equation:

$\alpha = \frac{\Delta\; m_{t,T}}{\Delta\; y}$ where Δm_(t,T) is the difference in mass at time t and temperature T; Δy is the derivative at the given cure temperature T. The derivative at 200° C. for soy-AAG and polyol-based resin is respectively 19.2 and 17.9%. Therefore, the degree of cure at 20 min for soy-AAG is 51%, and the degree of cure for the commercial bio-based polyol is 29%.

Performance data for the soy-AAG cured resin is illustrated in tabular format in FIG. 4. The corrosion performance of soy-AAG cured resin was evaluated using Electrochemical Impedance Spectroscopy (EIS). The coating was exposed to 3.5 wt % NaCl and the impedance was measured using a PAR potentiostat/galvanostat and Solartron equipment between the frequency range of 0.01 Hz to 65 Hz. The total coating impedance at a frequency of 0.1 Hz was used as a guide to predict the corrosion performance of the coating. The performance for the soy-AAG cured resin coating over a period of 50 days is shown in FIG. 5. It was evident that the soy-AAG cured resin is on par with the corrosion performance of BPA-based resin and outperforms commercial bio-based BPA-free alternative coatings.

The toxicity of soy-AAG cured resin was assessed using BG1LUC assay, as described in Bittner, et al., Environmental Heath, 2014, 13, 103. It was found that soy-AAG cured resin has no detectable estrogenic (see FIG. 6) or anti-estrogenic activity (see FIG. 7).

The resulting mixture was coated onto a low carbon steel panel using a 2 mm wet film thickness drawdown bar. The panel was cured at 180° C. for 30 min.

Example 3E—Arsoy-AAG Polyamine

A flask was charged with CYMEL™ 303 (2.5 g), Arsoy-AAG (7.5 g), p-toluene sulfonic acid (0.5% wt). The mixture was diluted with MEK (30% wt) and stirred until a uniform solution was achieved. The solution was spread onto a low carbon steel coupon (2 mm film thickness) and heated (cured) at 180° C. for 30 min. The resulting tackless coating appeared opaque and yellow in color.

Example 3F—Styrenyl-AAG Polyamine

A flask was charged with CYMEL™-303 (2.5 g), Styrene-AAG of Example 5A (2.5 g). Soy-AAG of Example 2A/2B (5.0 g) and p-toluene sulfonic acid (0.2 mol %). The reaction mixture was stirred until a uniform solution was obtained. The reaction mixture was spread onto a low carbon steel coupon (2 mm thick). The coupon and reaction mixture were heated at 180° C. for 30 min, resulting in a tackless yellow-brown film.

Prophetic Example 6: Acetoacetalation of Epoxidized Triglyceride

The byproduct t-butanol may be collected in the trap and the quantity of t-butanol produced may be indicative of the progression of the reaction.

To the extent that the term “include” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the interpretation of the term “comprising” when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When “only A or B but not both” is intended, then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. As used in the specification and the claims, the singular forms “a,” “an,” and “the” include the plural. As used herein, the term “approximately” means plus or minus 10% unless otherwise specified.

The terms “optional” and “optionally” mean that the subsequently described circumstance may or may not occur, so that the description includes instances where the circumstance occurs and instances where it does not.

In general, “substituted” refers to an organic group as defined below (e.g., an alkyl group) in which one or more bonds to a hydrogen atom contained therein are replaced by a bond to non-hydrogen or non-carbon atoms. Substituted groups also include groups in which one or more bonds to a carbon(s) or hydrogen(s) atom are replaced by one or more bonds, including double or triple bonds, to a heteroatom. Thus, a substituted group is substituted with one or more substituents, unless otherwise specified. In some embodiments, a substituted group is substituted with 1, 2, 3, 4, 5, or 6 substituents. Examples of substituent groups include: halogens (i.e., F. Cl, Br, and I); hydroxyls; alkoxy, alkenoxy, aryloxy, aralkyloxy, heterocyclyloxy, and heterocyclylalkoxy groups; carbonyls (oxo); carboxyls; esters; urethanes; oximes; hydroxylamines; alkoxyamines; aralkoxyamines; thiols; sulfides; sulfoxides; sulfones; sulfonyls; sulfonamides; amines; N-oxides; hydrazines; hydrazides; hydrazones; azides; amides; ureas; amidines; guanidines; enamines; imides; isocyanates; isothiocyanates; cyanates; thiocyanates; imines; nitro groups; nitriles (i.e., CN); and the like.

Substituted ring groups such as substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups also include rings and ring systems in which a bond to a hydrogen atom is replaced with a bond to a carbon atom. Therefore, substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups may also be substituted with substituted or unsubstituted alkyl, alkenyl, and alkynyl groups as defined below.

Alkyl groups include straight chain and branched chain alkyl groups having from 1 to 12 carbon atoms, and typically from 1 to 10 carbons or, in some embodiments, from 1 to 8, 1 to 6, or 1 to 4 carbon atoms. Examples of straight chain alkyl groups include groups such as methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, n-heptyl, and n-octyl groups. Examples of branched alkyl groups include, but are not limited to, isopropyl, iso-butyl, sec-butyl, tert-butyl, neopentyl, isopentyl, and 2,2-dimethylpropyl groups. Representative substituted alkyl groups may be substituted one or more times with substituents such as those listed above and include, without limitation, haloalkyl (e.g., trifluoromethyl), hydroxyalkyl, thioalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, alkoxyalkyl, carboxyalkyl, and the like.

Cycloalkyl groups include mono-, bi- or tricyclic alkyl groups having from 3 to 12 carbon atoms in the ring(s), or, in some embodiments, 3 to 10, 3 to 8, or 3 to 4, 5, or 6 carbon atoms. Exemplary monocyclic cycloalkyl groups include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and cyclooctyl groups. In some embodiments, the cycloalkyl group has 3 to 8 ring members, whereas in other embodiments, the number of ring carbon atoms ranges from 3 to 5, 3 to 6, or 3 to 7. Bi- and tricyclic ring systems include both bridged cycloalkyl groups and fused rings, such as, but not limited to, bicyclo[2.1.1]hexane, adamantyl, decalinyl, and the like. Substituted cycloalkyl groups may be substituted one or more times with non-hydrogen and non-carbon groups as defined above. However, substituted cycloalkyl groups also include rings that are substituted with straight or branched chain alkyl groups as defined above. Representative substituted cycloalkyl groups may be mono-substituted or substituted more than once, such as, but not limited to, 2,2-, 2,3-, 2,4-2,5- or 2,6-disubstituted cyclohexyl groups, which may be substituted with substituents such as those listed above.

Aryl groups are cyclic aromatic hydrocarbons that do not contain heteroatoms. Aryl groups herein include monocyclic, bicyclic and tricyclic ring systems. Thus, aryl groups include, but are not limited to, phenyl, azulenyl, heptalenyl, biphenyl, fluorenyl, phenanthrenyl, anthracenyl, indenyl, indanyl, pentalenyl, and naphthyl groups. In some embodiments, aryl groups contain 6-14 carbons, and in others from 6 to 12 or even 6-10 carbon atoms in the ring portions of the groups. In some embodiments, the aryl groups are phenyl or naphthyl. Although the phrase “aryl groups” includes groups containing fused rings, such as fused aromatic-aliphatic ring systems (e.g., indanyl, tetrahydronaphthyl, and the like), it does not include aryl groups that have other groups, such as alkyl or halo groups, bonded to one of the ring members. Rather, groups such as tolyl are referred to as substituted aryl groups. Representative substituted aryl groups may be mono-substituted or substituted more than once. For example, monosubstituted aryl groups include, but are not limited to, 2-, 3-, 4-, 5-, or 6-substituted phenyl or naphthyl groups, which may be substituted with substituents such as those listed above.

Aralkyl groups are alkyl groups as defined above in which a hydrogen or carbon bond of an alkyl group is replaced with a bond to an aryl group as defined above. In some embodiments, aralkyl groups contain 7 to 16 carbon atoms, 7 to 14 carbon atoms, or 7 to 10 carbon atoms. Substituted aralkyl groups may be substituted at the alkyl, the aryl or both the alkyl and aryl portions of the group. Representative aralkyl groups include but are not limited to benzyl and phenethyl groups and fused (cycloalkylaryl)alkyl groups such as 4-indanylethyl. Representative substituted aralkyl groups may be substituted one or more times with substituents such as those listed above.

Heterocyclic groups include aromatic (also referred to as heteroaryl) and non-aromatic ring compounds containing 3 or more ring members of which one or more is a heteroatom such as, but not limited to, N, O, and S. In some embodiments, the heterocyclyl group contains 1, 2, 3 or 4 heteroatoms. In some embodiments, heterocyclic groups include mono-, bi- and tricyclic rings having 3 to 16 ring members, whereas other such groups have 3 to 6, 3 to 10, 3 to 12, or 3 to 14 ring members. Heterocyclic groups encompass aromatic, partially unsaturated and saturated ring systems, such as, for example, imidazolyl, imidazolinyl and imidazolidinyl groups. The phrase “heterocyclic group” includes fused ring species including those comprising fused aromatic and non-aromatic groups, such as, for example, benzotriazolyl, 2,3-dihydrobenzo[1,4]dioxinyl, and benzo[1,3]dioxolyl. The phrase also includes bridged polycyclic ring systems containing a heteroatom such as, but not limited to, quinuclidyl. However, the phrase does not include heterocyclic groups that have other groups, such as alkyl, oxo or halo groups, bonded to one of the ring members. Rather, these are referred to as “substituted heterocyclic groups.” Heterocyclic groups include, but are not limited to, aziridinyl, azetidinyl, pyrrolidinyl, imidazolidinyl, pyrazolidinyl, thiazolidinyl, tetrahydrothiophenyl, tetrahydrofuranyl, dioxolyl, furanyl, thiophenyl, pyrrolyl, pyrrolinyl, imidazolyl, imidazolinyl, pyrazolyl, pyrazolinyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, thiazolyl, thiazolinyl, isothiazolyl, thiadiazolyl, oxadiazolyl, piperidyl, piperazinyl, morpholinyl, thiomorpholinyl, tetrahydropyranyl, tetrahydrothiopyranyl, oxathiane, dioxyl, dithianyl, pyranyl, pyridyl, pyrimidinyl, pyridazinyl, pyrazinyl, triazinyl, dihydropyridyl, dihydrodithiinyl, dihydrodithionyl, homopiperazinyl, quinuclidyl, indolyl, indolinyl, isoindolyl, azaindolyl (pyrrolopyridyl), indazolyl, indolizinyl, benzotriazolyl, benzimidazolyl, benzofuranyl, benzothiophenyl, benzthiazolyl, benzoxadiazolyl, benzoxazinyl, benzodithiinyl, benzoxathiinyl, benzothiazinyl, benzoxazolyl, benzothiazolyl, benzothiadiazolyl, benzo[1,3]dioxolyl, pyrazolopyridyl, imidazopyridyl (azabenzimidazolyl), triazolopyridyl, isoxazolopyridyl, purinyl, xanthinyl, adeninyl, guaninyl, quinolinyl, isoquinolinyl, quinolizinyl, quinoxalinyl, quinazolinyl, cinnolinyl, phthalazinyl, naphthyridinyl, pteridinyl, thianaphthyl, dihydrobenzothiazinyl, dihydrobenzofuranyl, dihydroindolyl, dihydrobenzodioxinyl, tetrahydroindolyl, tetrahydroindazolyl, tetrahydrobenzimidazolyl, tetrahydrobenzotriazolyl, tetrahydropyrrolopyridyl, tetrahydropyrazolopyridyl, tetrahydroimidazopyridyl, tetrahydrotriazolopyridyl, and tetrahydroquinolinyl groups. Representative substituted heterocyclic groups may be mono-substituted or substituted more than once, such as, but not limited to, pyridyl or morpholinyl groups, which are 2-, 3-, 4-, 5-, or 6-substituted, or disubstituted with various substituents such as those listed above.

Heteroaryl groups are aromatic ring compounds containing 5 or more ring members, of which one or more is a heteroatom such as, but not limited to, N, O, and S. Heteroaryl groups include, but are not limited to, groups such as pyrrolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, thiazolyl, pyridinyl, pyridazinyl, pyrimidinyl, pyrazinyl, thiophenyl, benzothiophenyl, furanyl, benzofuranyl, indolyl, azaindolyl (pyrrolopyridinyl), indazolyl, benzimidazolyl, imidazopyridinyl (azabenzimidazolyl), pyrazolopyridinyl, triazolopyridinyl, benzotriazolyl, benzoxazolyl, benzothiazolyl, benzothiadiazolyl, imidazopyridinyl, isoxazolopyridinyl, thianaphthyl, purinyl, xanthinyl, adeninyl, guaninyl, quinolinyl, isoquinolinyl, tetrahydroquinolinyl, quinoxalinyl, and quinazolinyl groups. Heteroaryl groups include fused ring compounds in which all rings are aromatic such as indolyl groups and include fused ring compounds in which only one of the rings is aromatic, such as 2,3-dihydro indolyl groups. Although the phrase “heteroaryl groups” includes fused ring compounds, the phrase does not include heteroaryl groups that have other groups bonded to one of the ring members, such as alkyl groups. Rather, heteroaryl groups with such substitution are referred to as “substituted heteroaryl groups.” Representative substituted heteroaryl groups may be substituted one or more times with various substituents such as those listed above.

Heteroaralkyl groups are alkyl groups as defined above in which a hydrogen or carbon bond of an alkyl group is replaced with a bond to a heteroaryl group as defined above. Substituted heteroaralkyl groups may be substituted at the alkyl, the heteroaryl or both the alkyl and heteroaryl portions of the group. Representative substituted heteroaralkyl groups may be substituted one or more times with substituents such as those listed above.

Groups described herein having two or more points of attachment (i.e., divalent, trivalent, or polyvalent) within the compound of the technology are designated by use of the suffix, “ene.” For example, divalent alkyl groups are alkylene groups, divalent aryl groups are arylene groups, divalent heteroaryl groups are heteroarylene groups, and so forth. Substituted groups having a single point of attachment to the compound of the technology are not referred to using the “ene” designation. Thus, for example, chloroethyl is not referred to herein as chloroethylene.

Alkoxy groups are hydroxyl groups (—OH) in which the bond to the hydrogen atom is replaced by a bond to a carbon atom of a substituted or unsubstituted alkyl group as defined above. Examples of linear alkoxy groups include, but are not limited to, methoxy, ethoxy, propoxy, butoxy, pentoxy, hexoxy, and the like. Examples of branched alkoxy groups include, but are not limited to, isopropoxy, sec-butoxy, tert-butoxy, isopentoxy, isohexoxy, and the like. Examples of cycloalkoxy groups include, but are not limited to, cyclopropyloxy, cyclobutyloxy, cyclopentyloxy, cyclohexyloxy, and the like. Representative substituted alkoxy groups may be substituted one or more times with substituents such as those listed above.

The term “amine” (or “amino”), as used herein, refers to NR^(a)R^(b) groups, wherein R^(a) and R^(b) are independently hydrogen, or a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl, aralkyl, heterocyclylalkyl or heterocyclyl group as defined herein. In some embodiments, the amine is alkylamino, dialkylamino, arylamino, or alkylarylamino. In other embodiments, the amine is NH₂, methylamino, dimethylamino, ethylamino, diethylamino, propylamino, isopropylamino, phenylamino, or benzylamino. The term “alkylamino” is defined as NR^(c)R^(d), wherein at least one of R^(c) and R^(d) is alkyl and the other is alkyl or hydrogen. The term “arylamino” is defined as NR^(e)R^(f), wherein at least one of R^(e) and R^(f) is aryl and the other is aryl or hydrogen.

The term “halogen” or “halo,” as used herein, refers to bromine, chlorine, fluorine, or iodine. In some embodiments, the halogen is fluorine. In other embodiments, the halogen is chlorine or bromine.
